Why can I not clone repository from Github using Cygwin SSH on Windows 7?

Question

I want to clone my own repository from Github using Git+Cygwin+Ssh.

How to do it - I create key, I publish public key on github.com, I do ssh-add?

What I am doing wrong?

$git clone git@github.com:ChameleonRed/test.git
Cloning into 'test'...
Warning: Permanently added the RSA host key for IP address '192.30.252.123' to the list of known hosts.
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

As you figured out you should use ssh keys. Follow those step to generate and use the keys under GitHub.

Here is how to set it up:

• Generate a new ssh key (or skip this step if you already have a key as you mentioned )
  ssh-keygen -t rsa -C "your@email"

• Once you have your key set in home/.ssh directory (or Users/<your user>.ssh under windows), open it and copy the content to the relevant section (ssh keys) under your central repository.

How to set up ssh key under your GitHub account?

• Login to GitHub account
• Click on the rancher on the top right (Settings)
  
• Click on the SSH keys and GPG Keys
  
• Click on the New SSH key
  
• Paste your key and save

Note

After the first set up open terminal and run a git fetch so the key will be tested and added to your known hosts file.
